   A company runs a web application on EC2 instances behind an Application Load Balancer. The security team wants to restrict access to the application so that only users from the company's corporate network can access it. The corporate network uses a range of public IP addresses. Which configuration should be implemented?

   • AConfigure the ALB to only listen on a private IP address
   • BConfigure the instance security group to allow inbound traffic only from the corporate IP range
   • CConfigure the ALB security group to allow inbound traffic only from the corporate IP range
   • DUse AWS WAF to block all IP addresses except the corporate range

   A company runs a fleet of EC2 instances in two Availability Zones behind an Application Load Balancer. The instances in one Availability Zone are receiving significantly more traffic than the other, causing performance issues. The company wants to ensure that traffic is distributed evenly across all instances in both Availability Zones. Which configuration should be enabled?

   • AIncrease the health check interval
   • BEnable cross-zone load balancing on the load balancer
   • CEnable sticky sessions on the target group
   • DAdd more instances to the underutilized Availability Zone
